Which of the following causes populations to shift most quickly from an exponential to a logistic population growth?

a. favorable climatic conditions

b. removal of predators

c. decreased death rate

d. competition for resources

d. competition for resources

Explanation:

Exponential population growth is a growth which constantly increase (growth rate is the same no matter how large population is). It is the type of growth in which resources are unlimited (that is rare case) and a great example is bacterial growth. On the other hand, logistic growth decrease as resources become limited. Carrying capacity is the limit that population reaches.

So, when there is competition for resources in the population, at a certain point of time population will reach its carrying capacity and limit the growth.

Exponential growth is represented with J-shape, while logistic is represented with S-shape.
